Inferno

Spell Type: Attack; Mana Cost: 20 MP; TN: 19
Test: Dexterity (Acrobatics) vs Spellpower; Requirements: Fireball

Calling upon the raw elements of creation, you ignite a column of air 15 feet in radius and 30 feet tall anywhere within 100 feet. Anyone, whether ally or enemy, who enters the inferno or starts their turn in it, suffers 3d6 + Magic damage. Targets who make a successful Dexterity (Acrobatics) test vs. your Spellpower suffer only 2d6 damage but fall prone. Additionally, any target that leaves the column of fire continues to burn, taking 1d6 damage at the start of their turn until they succeed on a Dexterity (Acrobatics) test vs. your Spellpower to put out the flames. The column normally lasts a single round, but you can extend its duration another round by spending 10 MP at the start of your subsequent turns as a free action.
